In One Chart: The government shutdown has become the longest on record

At 22 days in duration as of Saturday, the current partial government shutdown has become the longest one on record, based on figures that go back more than 40 years.

It has exceeded the mark set by a 21-day closure during the Clinton administration that began in December 1995.

The record was broken as the end of the workweek brought no major signs of a bipartisan spending deal that would reopen shuttered agencies.

The chart below, based on Congressional Research Service data, shows how the current shutdown tops all other closures or gaps in funding in the last four decades.

Analysts have noted that the impact of the current shutdown is somewhat limited, as it’s affecting agencies that represent about 25% of total government spending.

The ongoing shutdown has been sparked by a dispute over money for President Donald Trump’s proposed wall at the southern border. The president on Wednesday left a negotiating session after clashing with top Democratic lawmakers, and Trump stated Thursday that he could declare a national emergency in order to build his wall if there’s no funding deal with Democrats, saying “probably I will do it. I would almost say definitely.” On Friday he backed away from any imminent national-emergency declaration but said he retained the right to take such a step. “I’m not going to do it so fast,” he said, according to a White House pool report.

Shutdown-related worries have played a role in sending the stock market SPX, -0.01% sharply lower in recent weeks. The Dow DJIA, -0.02% has rallied 2.9% in January, but it is still showing a loss of 1.5% over the past 30 days.
